Structure of the catalytic domain of MCR-1 phosphoethanolamine transferase. Secondary structure elements are depicted as a ribbon model and colored in cyan (helices), purple (strands), and salmon (loops). Additionally, the phosphothreonine 285 is represented in sticks. Right, rotated 90 °, a view of the characteristic alkaline phosphatase α/β/α fold of cMCR-1
